Abstract

Patente de Invenção: <B>"CARTãO COM MEMóRIA SEM CONTATO COM ADAPTAçãO DE SINAIS DE COMANDO"<D>. O cartão com memória sem contato é destinado a ser eletromagneticamente acoplado a uma estação distante para comunicar dados com a estação. O cartão compreende uma interface sem contato (IEA), apta a se comunicar com a estação, segundo um protocolo de comunicação assíncrono, e meios de tratamento de dados, próprios para memorizar dados em uma memória e controlar o acesso à memória. Os meios de tratamento (UTS) são ajustados para dialogar segundo um protocolo de comunicação síncrona. O cartão (CSC) compreende, além disso, meios adaptadores (ADA) próprios para adaptar os sinais assíncronos dos meios de tratamento (UTS) e vice-versa, a fim de permitir aos meios de tratamento síncronos (UTS) se comunicarem com a estação, via uma interface de comunicação, sem contato assíncrono (IEA).Invention Patent: <B> "CARD WITH MEMORY WITHOUT CONTACT WITH ADAPTATION OF COMMAND SIGNS" <D>. The non-contact memory card is intended to be electromagnetically coupled to a distant station to communicate data with the station. The card comprises a non-contact interface (IEA), able to communicate with the station, according to an asynchronous communication protocol, and means of data processing, suitable for storing data in a memory and controlling access to memory. The means of treatment (UTS) are adjusted to dialogue according to a synchronous communication protocol. The card (CSC) also includes adapter means (ADA) to adapt the asynchronous signals of the treatment means (UTS) and vice versa, in order to allow the synchronous treatment means (UTS) to communicate with the station , via a communication interface, without asynchronous contact (IEA).
